摘要: A near-infrared tunable diode laser spectrometer called TDLAS has been developed that combines telecommunication-type as well new-generation antimonide diodes to measure C2H2, H2O, CO2 and their isotopologues in the near infrared. This sensor is devoted situ analysis of soil Martian satellite PHOBOS, within framework Russian space mission PHOBOS-GRUNT. In first part paper, we report accurate spectroscopic measurements C2H2 13C12CH2 1.533 μm, H2O at 2.682 μm 13C16O2 16O12C18O 2.041 μm H2 17O, 18O HDO 2.642 μm. The achieved line strengths are thoroughly compared data from molecular databases or former experimental determinations. second describe for PHOBOS-GRUNT mission.
